Refined to Perfection
Africa's pioneer 24-karat gold refinery — from ore to 99.99% certified bullion.
Setting the international gold standard across Central Africa
MOUHDJAF MINING TRANSFORMATION (MOUHDJAF-MT SARL) stands as the very first 24-karat gold refining unit established within the Central African sub-region — founded to answer the strategic national initiatives of the State of Cameroon.
Our operations span raw extraction, spectroscopic analysis, legal appraisal, industrial smelting and ultra-purity refining — deployed across Cameroon, Niger and the Central African Republic.
One group, two companies
MOUHDJAF brings together two complementary companies covering the full gold value chain — from the mine to the certified bar.
MOUHDJAF MT SARL
The Cameroonian mining company — geological exploration, industrial mining, refining and local transformation of mineral resources.

High-yield gold assets & strategic permits
Entrepreneurship is a solution to reduce unemployment in Cameroon and across several African nations. The mining sector holds tremendous assets through its branches — exploration, extraction and transformation.
Responsibly conducted mining is a powerful engine of sustainable growth for our countries — beyond its impact on direct and indirect employment, livelihoods and the national economy.
A mining operation must benefit every stakeholder economically and socially: the State, the workers, and the local population.
Powered by EMAK MAKINA — 40+ years of Turkish metallurgy
An exclusive alliance providing automated infrastructure, clean gas-neutralization technology and continuous technical training — ensuring international standard quality benchmarks.
